ROUGHT, to some degree, is experienced almost every D year in the southeastern United States because of poor distribution of rainfall. More than half of the average annual rainfall of approximately 50 inches in this area occurs in winter months. The past two years have demonstrated that such droughts may be of long duration and of serious consequence. The shortage of pasture and hay throughout these drought-stricken areas has placed increased emphasis upon the need for drought-resistant .grasses and legumes in the Southeast. The studies reported here were begun in an effort to appraise the relative drought resistance or drought escapement of several Southern pasture grasses.
